+ \brief This is the base class for all elements in the project tree.
+
+ All widgets and other types in the project are derived from Fl_Types. They
+ are organized in a doubly linked list. Every Type also has depth information
+ to create a pseudo tree structure. To make walking up the tree faster, Type
+ also holds a pointer to the `parent` Type.
+
+ Types can be identified using the builtin ID system that works like RTTI. The
+ method `id()` returns the exact type, and the method `is_a(ID)` returns true
+ if this is the exact type or derived from the type, and a dynamic cast will
+ work reliably.
+
+ \todo it would be nice if we can handle multiple independent trees. To do that
+ we must remove static members like `first` and `last`.

+ on pointer manipulation. Or use std in future releases.
